Sinus of Valsalva aneurysms are rare cardiac abnormalities that may be congenital or acquired. Patch closure or direct closure of the aneurysm orifice is a frequently performed surgical repair strategy. In this report, we present a rare case of an isolated giant right sinus of Valsalva aneurysm with aortic insufficiency and right coronary artery obstruction. We treated this patient by a valve-sparing aortic root remodelling procedure with partial preservation of the intact Valsalva sinuses and coronary artery bypass grafting with a favourable outcome...

There is evidence that high surgical volume and team consistency improve outcomes. Mortality of 4%-12% for aortic root surgery has been reported in the United States and UK. We aim to assess outcomes of patients undergoing aortic root surgery by a consistent, high-volume team. Data on patients undergoing elective or urgent aortic root replacement (ARR) were collected prospectively. Patients undergoing emergency surgery were excluded. A standardized perioperative approach was maintained and was achieved by delivering training to team members, including surgical trainees, anesthetic, nursing, and perfusion staff, whenever there was a change of team...

Valve-sparing aortic root replacement remains challenging for patients with eccentric severe aortic regurgitation when the cusps are totally asymmetric. We report a case of successful reimplantation operation for such a lesion. Because free margin lengths from commissure to Arantius body of the adjacent two cusps were matched while inter-commissural distances were totally different, right coronary cusp prolapse was corrected by asymmetrically aligning the position and height of three commissures without cusp plication...

OBJECTIVES: This study aims to examine the feasibility and clinical course after minimally invasive David procedure compared with those via a conventional median sternotomy. METHODS: One hundred and ninety-two consecutive patients who underwent elective valve-sparing aortic root replacement (David procedure) with or without additional cusp repair for aortic regurgitation (n = 17, 8.9%), dilatation of the aortic root (n = 95, 49.5%) or a combination of both pathologies (n = 80, 41...

Transcatheter aortic valve implantation (TAVI) is an emerging treatment for high-risk patients with aortic stenosis. Aortic regurgitation is considered to be a relative contraindication for transcatheter procedures, as a non-calcified aortic annulus poses the risk of an insufficient anchoring of the transcatheter aortic valve prosthesis. Herein is described the case of a patient who suffered from recurrent aortic valve regurgitation after valve-sparing repair, and which was successfully treated by the transcatheter implantation of an Edwards SAPIEN 3™ prosthesis...

REVIEW
Emile Bacha
This review deals with a relatively new field in congenital heart surgery, valve preservation or, in cases of more severe pulmonary valve stenosis or dysplasia, valve reconstruction during tetralogy of Fallot repair. We describe the stepwise approach utilized, starting with simple maneuvers such as commissurotomy and valve dilation for mild pulmonary stenosis to commissurotomy and intraoperative balloon dilation for moderate stenosis, and finally transection of the annulus and valve reconstruction using a patch that acts as a modified monocusp...

Valve-sparing aortic root replacement has been utilized in children with aneurysms of the proximal aorta as a valid alternative to composite mechanical or biologic prostheses. While the majority of pediatric patients with aortic root aneurysms have various forms of connective tissue disorders, other diagnostic groups have emerged, such as patients with various forms of congenital heart disease and non-syndromic thoracic aortic aneurysms. We present our experience with valve-sparing procedures in pediatric patients, highlighting the technical aspects of the operation as well as some of the pitfalls and complications we have encountered over the last two decades...

Reoperations after the Ross procedure are rare, with autograft as well as homograft failure being the dominant causes for redo cardiac procedures. Due to increasing experience with valve-sparing aortic valve procedures, more valves can be preserved during redo surgery. Herein are reported the details of a patient who underwent quadruple valve reoperation comprising redo with a reconstructive approach after the short-term failure of pulmonary autograft and homograft with concomitant mitral and tricuspid regurgitation...

BACKGROUND: Operative choices for aortic root disease include traditional root replacement with a composite valved graft as well as various valve-sparing and root repair procedures. OBJECTIVES: To report our experience with traditional composite graft aortic root replacement by a single surgeon over a 25-year period in 449 patients, focusing on long-term survival and freedom from late reoperation and adverse events. METHODS: The coronary button technique was used in all patients...

The original valve-sparing procedures for aortic root aneurysms were remodeling and reimplantation of the aortic root. The remodeling technique provides more physiologic movement of the cusps within 3 reconstructed neo-sinuses, thus preserving root expansibility through the interleaflet triangles. However, the durability of remodeling has been a matter of concern due to the high rate of aortic insufficiency when annular dilation is not addressed. Therefore, a modified approach was developed, combining a physiologic remodeling of the root with a subvalvular annuloplasty...

OBJECTIVE: Little is known about the outcomes of aortic root operations that involve inducing hypothermic circulatory arrest for relatively extensive proximal aortic surgery. We attempted to identify predictors of postoperative hospital length of stay (LOS) and factors that affect postoperative recovery. METHODS: During 2006-2014, 247 of 265 patients (93.2%) with disease extending into the aortic arch survived aortic root operations (206 elective, 41 urgent/emergent) in which hypothermic circulatory arrest with moderate hypothermia was used...

BACKGROUND: Valve-sparing root replacement (VSRR) is an established therapy for aortic root pathology. Limited insight exists when the results of VSRR are compared with those of conventional root replacement with use of a bioprosthetic composite conduit (BIO). This study compares the operative and midterm results of VSRR and BIO. METHODS: A retrospective review from 2002 to 2015 at a United States academic center identified 282 patients who underwent VSRR and 425 patients who underwent BIO...

Background The aim of this study was to evaluate long-term dilatation of Hemashield Gold and Hemashield Platinum vascular prostheses in ascending aortic position using different measurement methods to obtain precise results. Methods Between 1999 and 2007, 73 patients with Stanford type A dissection received ascending aortic replacement with Hemashield Gold and Hemashield Platinum prostheses. Measurements were performed using multiplanar reconstruction mode of electrocardiogram (ECG)-gated, multislice spiral computed tomography (MSCT) in strictly orthogonal cross-sectional planes...

OBJECTIVES: Early experience with Loeys-Dietz syndrome (LDS) suggested an aggressive aortopathy with high risk of aneurysm dissection and rupture at young ages and at smaller aortic diameters than in other connective tissue disorders. We reviewed our experience with LDS to re-examine our indications and outcomes of surgical management. METHODS: We reviewed all patients with a diagnosis of LDS who underwent cardiovascular surgery at our institution. The primary endpoint was mortality, and secondary endpoints included postoperative complications and need for reintervention...

OBJECTIVE: Excellent outcomes have been established for elective aortic root replacement (ARR). It is less clear whether extending the repair into the proximal aortic arch with hypothermic circulatory arrest increases risk. We examined the early outcomes of elective, primary ARR, with and without hemiarch replacement, in patients without previous cardiac surgery. METHODS: Over a 4-year period, 140 non-redo patients (median age, 54 years) underwent elective, primary ARR for root aneurysms; 119 patients (85%) had hemiarch replacement, and 21 (15%) had only ascending aortic replacement...

BACKGROUND: Patients undergoing hybrid aortic arch reconstruction require careful protection of vital organs. We believe that whole body perfusion with tailored dual circuitry may help to achieve optimal patient outcomes. METHODS: Our circuit has evolved from a secondary circuit utilizing a cardioplegia delivery device for lower body perfusion to a dual-oxygenator circuit. This allows individually controlled regional perfusion with ease of switching from secondary to primary circuit for total body flow...
